linux-next: build failure after merge of the apparmor tree
From: Stephen Rothwell

Hi all,
After merging the apparmor tree, today's linux-next build (x86_64
allmodconfig) failed like this:
security/apparmor/af_unix.c: In function 'unix_state_double_lock':
security/apparmor/af_unix.c:627:17: error: implicit declaration of function 'unix_state_lock'; did you mean 'unix_state_double_lock'? [-Wimplicit-function-declaration]
627 | unix_state_lock(sk1);
| ^~~~~~~~~~~~~~~
| unix_state_double_lock
security/apparmor/af_unix.c: In function 'unix_state_double_unlock':
security/apparmor/af_unix.c:642:17: error: implicit declaration of function 'unix_state_unlock'; did you mean 'unix_state_double_lock'? [-Wimplicit-function-declaration]
642 | unix_state_unlock(sk1);
| ^~~~~~~~~~~~~~~~~
| unix_state_double_lock
Caused by commit
c05e705812d1 ("apparmor: add fine grained af_unix mediation")
interacting with commit
84960bf24031 ("af_unix: Move internal definitions to net/unix/.")
from the net-next tree.
I have applied the following patch for today.
